Influence of Early to Late Energy Ratios on Subjective Estimates of Small Room Acoustics

This paper continues the research on "Subjective and Objective Evaluation of Listening Room Acoustics" reported at the 102nd and 103rd AES Conventions. Acoustical characteristics of 17 listening rooms and home theaters were measured and analyzed for possible acoustic improvements. Early to late energy ratios (C5, C10, C15, C20, C35, C50, C80) were measured, calculated by TEF-20 (MLS) in the 63-16000 octave bands and compared with their subjective estimates of speech and music quality.
